PLANTING DEVICE FOR CORN-PLANTERS.

To all whom t may concern:

Be it known that we, HENRY F. RUEL, residing at Kankakee, EMILE SEAUBIN, re.- siding in Ganeer township, and WAYNE I-I. DYER and CLIFFORD B. SAWYER, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Planting Devices for Corn-Planters, of which the following is a specification.

This invention relates to improvements in corn planters and more particularly to the plate changing and dropping apparatus.

The improvements will be hereinafter fully set forth in the specication and more particularly pointed out in the appended i claim.

In the accompanying drawings z-F igurev 1 is a plan view. Fig. 2 is a perspective view. Fig. 3 is an enlarged horizontal section taken on line 3 3 of Fig. 1. Fig. t a similar View taken o-n line 1 4 of Fig. 1. Fig. 5 is a section taken on line 5-5 of Fig. 1 and Fig. 6 is a sectional view taken on line 6-6 of Fig. 4:.

teferring to the drawings'for a more particular description of the invention and which drawings are for illustrative purposes only and are therefore not drawn to scale, 1 indicates a door a slide in the dropping channel 2 operated by the check rower bar 3 after a certain number of kernels have been dropped upon the door.

/1 indicates the dropping plate or disk in the bottom of the hopper 5 which is turned or rotated by the turning disk 6 provided on its top face with a series of turning lugs 7, which, when the hopper is in operative position, engage lugs 8 on the dropping plato.

9 indicates the supporting plate for the hopper, which plate is provided with the forked extension 10 by means of which it is pivoted to the frame of the machine in position to swing in a vertical plane from an operative to an inoperative position or vice versa.

"With the hopper and hopper supporting plate in the position shown in Fig. 2, all that is necessary to make an exchange in the dropping plates is to remove the one in use and substitute a new plate. The plate may be removed by simply lifting it out of the bottom of the hopper. When the eX- change has been made, the hopper support- Speccation of Letters Patent.

ing plate is swung back into normal or operative position upon the turning disk, and the hopper or seed box dropped back on the hopper supporting plate. The hopper and supporting plate are then secured in operative position by the pivoted screw 11 provided with the wing nut 12. The screw is pivoted to the bearing 13 suitably attached to the frame o-f the machine and when adjusted to secure the plate yand hopper engages a recess 14 formed in theeXtension 15 of the plate and a recess 16 inthe edge of the lug 17 of the hopper. The wing nut is turned to extend across the recess of the lug` 17, as will be obvious.

It will be observed from the foregoing that an exchange in the dropping plate may bel effected with the minimum time and labor, and in this respect our improvements have a great advantage over all other known means of holding the plate in position as it is now necessary to remove from tive to seven separate parts before the plate can be reached. ItI will be understood that there is a turning disk and hopper supporting plate at each side of the machine. The revolutions of the turning disks are regulated by the shaft- 18, provided at opposite ends with the gears 19 which intermesh with teeth 20 on the bot-tom faces of the turning disks. This shaft in ordinary planters makes a full revolution between the individual operations of the check rower bar, but in this device there is provided the clamp 21 having the inwardly projecting port-ion 22 disposed in the path of lugs 23 arranged at diametrically opposite points on the periphery of the disk 24 carried by the shaft 18 and rotated by the sprocket gear 25 to which power is communicated from the main axle by the sprocket chain 26.

In practice, when the check rower bar operates, the inwardly projecting portion 22 the clamp is moved out of the path of the adjacent lug 23 when the shaft 18 is permitted to make a half revolution at the conclusion of which the other lug has been brought into position to engage the projecting portion of the clamp, it being under- 1 stood that during the half revolution of the shaft 18, the check rower bar has operated and returned to initial position to again bring the projecting portion of the clamp in the path of the lugs. This device insures absolute regularity in the number of kernels dropped on the door I in the dropping channel before the door is released to allow the kernels to drop to the ground.

From the foregoing description taken in connection with the drawings, it is thought that the construction and operation of the device will be understood without requiring a more extended explanation.

Various changes in the form, proportions and minor details of construction may be resorted to without departing from the principles or sacriicing any of the advantages of this invention as delined in the appended claim.

IVe claim- In a corn planter, a hopper, a dropping plate in the bottom of the hopper, a turning disk for the dropping plate, an operating shaft for the turning disk, a gear on the shaft, teeth on the turning disk to engage those of the gear, a slide in the dropping channel, a check rower bar for operating the slide to permit the kernels to fall on the ground, a turning disk for the shaft provided at diametrically opposite points with 25 stop lugs, a clamp carried by the check rower bar and provided with an inwardly projecting portion normally disposed in the path of the lugs, and means for transmitting power to the turning disk on the shaft to 30 turn the latter, the lugs on the turning disk and the projecting portion of the clamp permitting the shaft to make but a half-revolution to each operation of the check rower bar whereby the number ot kernels per- 3.5 mitted to drop on the slide in the dropping channel at each operation of the check rower bar is regulated.

In testimony whereof we aiiiX our signatures in presence of two witnesses.
